Benefits of technology

[0031]It has proven to be especially advantageous when the sensor unit is designed to record a mechanical stress at the base body. This can be utilized for determining, in particular, loads in the region of the first and second terminals of the first electrical device and the second electrica

Problems solved by technology

Even though the prior art has proven itself, there are nonetheless problems, in particular for use in motor vehicles.
This poses an obstacle and is undesired especially in the field of electromobility.
Moreover, the large structural form and the heavy weight lead to problems, especially in the field of electromobility in regard to exposure to vibrations and impacts, such as those usually occurring during the intended operation of motor vehicles.
Although it is possible in this way to

DETAILED DESCRIPTION OF THE DRAWINGS

[0043]FIG. 1 shows, in a perspective schematic illustration, an excerpt of a high-voltage battery system 42 of an electrically driven motor vehicle, which is not illustrated further. A current cable 40 of the high-voltage battery system 42 serves for the electrical connection of the high-voltage battery system 42 to an electrical system of the motor vehicle, which is not illustrated in further detail. The motor vehicle is driven by means of an electric drive, which is supplied for this purpose with electrical energy by the high-voltage battery system 42. In the present case, it is further provided that the electrical energy is supplied not only for the drive device for the purpose of acceleration of the motor vehicle, but, at the same time, also takes up electrical energy during a decelerating operation, that is, stores electrical energy in the high-voltage battery system 42.

[0044]The electric conductor 40 is guided through a toroidal transformer ...

Abstract

An electrical bus bar for conveying an electric current from a first electrical device to a second electrical device, with a base body, which is formed from an electrically conductive material, and which has a first terminal for connection to the first electrical device and a second terminal for connection to the second electrical device. A sensor unit with a fastening surface has at least one sensor element for detecting or recording a physical parameter of the bus bar. The base body has a support surface, to which the sensor unit is fastened by its fastening surface.

Description

FIELD[0001]The present invention relates to an electrical bus bar for conveying an electric current from a first electrical device to a second electrical device, with a base body formed from an electrically conductive material, which has a first terminal for connection to the first electrical device and a second terminal for connection to the second electrical device. The invention further relates to a battery with at least two battery cells, wherein each of the battery cells has two electrodes, which interact electrochemically with each other, wherein each of the electrodes has a terminal contact, wherein at least one terminal contact of one of the battery cells is connected in an electrically conductive manner to a terminal contact of the other of the battery cells by means of an electrical bus bar, wherein the electrical bus bar has a base body formed from an electrically conductive material. Finally, the invention also relates to a motor vehicle with an electrical system, which ...
